Advanced Foam Core Materials For Mission-Critical Applications

For over 50 years, Evonik’s ROHACELL® structural foams have been expanding the possibilities of lightweight composites.

ROHACELL® foams feature exceptional mechanical strength at ultra-low densities, and are ideal for use in defense and security applications, where reliable performance, durability and weight efficiency are crucial.

Additionally, rigid, continuous testing and quality control measures help ensure ROHACELL® foams meet military-grade standards like MIL-PRF-46194, WL5.1460 and WL5.1461.

Application Areas

Stealth applications

The unique dielectric properties and its ability to absorb radar waves, make ROHACELL® EC a superior foam material for stealth aircraft. Additional support is available for tailoring the material to precise requirements and for use in classified applications.

Evonik performance foams support advanced fighter aircraft systems with excellent dielectric properties, low weight and long‑term reliability for defense aviation applications.

Airplanes

Whether in wings, bulkheads or other structural components, there is a ROHACELL® foam core for the job. A key material used for decades in OEM manufacturers, our foams can be customized to meet the precise standards of all types of commercial or military fixed-wing aircraft.

Evonik performance foams enhance helicopter radar and sensor systems with lightweight, durable and radar‑transparent materials designed for demanding aerospace environments.

Helicopters

ROHACELL® cored components feature a closed cell structure, high specific strengths and an isotropic nature that is optimal for high-performance, rotary-wing.

Unmanned Aerial Vehicles (UAV) / Unmanned Aircraft Systems (UAS)

ROHACELL® foam cores are the ideal lightweight choice for composite structures in aerial vehicles, prototypes and unmanned aircraft. Mechanically dependable and highly temperature resistant, ROHACELL® air mobility foam grades can be made to your specific needs.

Evonik performance foams enable reliable radar system performance by offering lightweight, durable and radar‑transparent materials for aerospace and defense applications.

Communications/ Radar

The ultrafine cell structure in ROHACELL® foams offers high permittivity for efficiency, and is ideal for precision shaping for protecting the most sensitive radar and antenna devices.

Evonik performance foams offer rugged, lightweight and impact‑resistant material solutions for military land vehicles operating in harsh environments.

Land Vehicles and Watercraft
